An attempt to define terms:
Psychic Bid: A call which
deliberately and
grossly misrepresents the player's high-card strentgh and/or suit length. For example opening 1
♠ with a stiff or 6 HCP. This is the ACBL's official definition.
Tactical Bid: A call which
deliberately but
not grossly misrepresents the player's high-card strength or suit length.
Strategic Psychic: A psychic bid made because the bidding situation makes the odds of success favorable. Ben's example is a good one.
Destructive Psychic: A psychic bid made without regard to chances of success or in spite of high probability of failure in order to randomize results or disconcert opponents. Example overcalling a Precision 1
♣ with 1
♠ regardless of your strength or spade length, when your partnership agreement is that 1
♠ is natural or some other convertion. (If overcalling 1
♠ in this fashion
is your partnership agreement, this is legally a
Destructive Convention--it isn't any form of psychic.)
